Description
The Lennox 62K50 is an OEM Dual Rod Flame Sensor Kit engineered to deliver dependable flame detection and verification in compatible Lennox heating systems. Flame sensors are a critical safety component in gas furnaces — they confirm the presence of a burner flame and signal the control board to keep the gas valve open. A faulty or degraded flame sensor can cause nuisance lockouts, short cycling, and system shutdowns, making timely replacement essential for uninterrupted comfort and safe operation.

Why Replace Your Flame Sensor?
Over time, flame sensor rods can accumulate oxidation and carbon buildup that weakens the microamp signal sent to the control board. When the signal drops below the control board’s threshold, the board shuts off the gas valve as a safety precaution — even if the burner is lit. Replacing the sensor kit with a genuine Lennox OEM part restores proper signal strength and eliminates nuisance shutdowns.
